the reason why people are opposed to an overpowered PC is because then nothing is a challenge unless you crank it up to hardest difficulty.. i would like to be playinga game with more than just a varying level of easiness.. it would seem wrong to have a bunch of highlevel perks so you can go mano a mano against alduin
The problem with what you're saying is that some people want to be like that, they want to be overpowered.
Bethesda shouldn't impose limits on everyone (to a certain extent) I obviously would not want to be able to one-shot everything unless I've put in hundreds of hours of play time, and studied the mechanics thoroughly. If you like a challenge then it should be easy to impose limits on yourself (either by forcing yourself to not pick something you would see as "Overpowered" or by modifying the difficulty setting (or both)).
Basically what I'm saying is this: I prefer people imposing limits on themselves than to Bethesda imposing limits on everyone.
